(57) For use with a boost converter having first, second and third input inductors (La, Lb, Lc), a switching network includes first and second switches (S1, S2) coupled between
corresponding rails of the boost converter. The switching network also includes first,
second and third L-C resonant networks (L1-L3, Ca,Cb,Cc) wye-coupled to a node located between the first and second switches and coupled
to the first, second and third input inductors, respectively. The first and second
switches and the first, second and third L-C resonant networks cooperate to create
resonant voltages across, and induce phase currents through, the first, second and
third input inductors to reduce input current THD associated with the boost converter.
